<p>PROBLEM TO BE SOLVED: To solve the problem in which, while a CFBG is known as a dispersion compensation element, since a dispersion amount provided by a regular CFBG is too large compared to a dispersion amount generated in a resonator, it is not possible to appropriately compensate a dispersion of a resonator.SOLUTION: By using a dispersion amount of a finite difference obtained by combining CFBGs having different signs of dispersion, a dispersion generated in a resonator is compensated. By integrating a dispersion controlling mechanism, a dispersion amount may be arbitrarily controlled and a desired pulse width may be obtained.</p> |
